Why this isn't working:

Code:

int lParam = MapVirtualKey(VK_NUMPAD1, MAPVK_VK_TO_VSC) << 16;
lParam |= 0x00000001;
PostMessage(hDROD, WM_KEYDOWN, VK_NUMPAD1, lParam);
lParam |= 0xC0000001;
PostMessage(hDROD, WM_KEYUP, VK_NUMPAD1, lParam);

Spy++:
My code:

Code:

<00001> 007507A2 P WM_KEYDOWN nVirtKey:VK_NUMPAD1 cRepeat:1 ScanCode:4F fExtended:0 fAltDown:0 fRepeat:0 fUp:0
<00002> 007507A2 P WM_KEYUP nVirtKey:VK_NUMPAD1 cRepeat:1 ScanCode:4F fExtended:0 fAltDown:0 fRepeat:1 fUp:1

Real keyboard:

Code:

<00021> 00430788 P WM_KEYDOWN nVirtKey:VK_NUMPAD1 cRepeat:1 ScanCode:4F fExtended:0 fAltDown:0 fRepeat:0 fUp:0
<00022> 00430788 P WM_KEYUP nVirtKey:VK_NUMPAD1 cRepeat:1 ScanCode:4F fExtended:0 fAltDown:0 fRepeat:1 fUp:1

The messages are getting thru, but nothing happens in the other window?

..Do you know what's the point of it? It sets the scancode and I've confirmed that with scancode 0x00 it doesn't work.

Guess I'll have to focus on the app and then just SendInput.

EDIT: SendInput seems to fail too, altho it's return value is indicating that it succeeded. O_o Hmm.. OnScreen keyboard seems to work. I wonder if the game is processing input directly from keyboard.

So, I think the question is now how to send input to SDL based game?

You sure the game doesn't use DirectInput?

That's what I'm guessing too.. I'm not very familiar with SDL input, I'll check out later when I've time.

On Screen Keyboard (the one that ships with Win XP) uses SetWindowsHookEx. _________________ Mutilated lips give a kiss on the wrist of the worm-like tips of tentacles expanding in my mind I'm fine accepting only fresh brine you can get another drop of this yeah you wish

I wish it's source was available, darn MS.

Anyway.. Success! You need to use this keymap instead of VK_*: http://msdn.microsoft.com/en-us/library/ms835979.aspx .
So yea, noz3001, DirectInput ;) Oh yeh.. With SendInput.
